Description

Technical Field

[0001] The utility model relates to the technical field of electronic scale elastic body structures, in particular to an elastic body structure for electronic scales. Background Art

[0002] Chinese patent publication number CN218822664U discloses an elastomer structure for an electronic scale sensor, comprising a base and an elastomer body, one end of the elastomer body being a force-bearing end and the other end being a fixed end. A strain gauge slot is provided on the side end face of the elastomer body, a cable is provided on the upper end face of the elastomer body, a first fixing clip is provided on the upper end face of the base, and a second fixing clip is provided on the fixed end of the elastomer body. The elastomer body and the base are slidably connected by the first and second fixing clips. The side end face of the first fixing clip is provided with a through hole, and the side end face of the second fixing clip is provided with a screw hole, in which a bolt is provided. The utility model uses the first and second fixing clips to match and fix the two with bolts perpendicular to the force direction, so that the base and the elastomer body can only slide in the front-to-back direction without being offset in the longitudinal direction. This ensures that even when the bolts are loosened, the base and the elastomer body can still cooperate well.

[0003] However, the inventors have discovered that when the force is too great, the elastomer will exceed its elastic limit, resulting in permanent deformation or rupture. This is because the existing elastomer structure for electronic scales does not have an anti-overload structure. Therefore, we have proposed an elastomer structure for electronic scales.

[0017] (3) Beneficial effects

[0018] Compared with the prior art, the present invention provides an elastic body structure for electronic scales, which has the following beneficial effects:

[0019] 1. The electronic scale uses an elastic structure and an anti-overload structure. When the pressure is transmitted to the anti-overload structure, the pressure seat bears the pressure and disperses the pressure to the elastic member. At the same time, the convex plate on the pressure seat slides along the inner cavity of the slide groove and drives the overload column to move toward the bottom wall of the inner cavity of the deformation cavity. The overload column and the bottom wall of the inner cavity of the deformation cavity form a rigid support to prevent the elastomer from being damaged by overload and improve the protection performance, thereby preventing the elastomer from being damaged by overload, thereby improving its protection performance.

[0020] 2. The electronic scale uses an elastic structure. By setting an elastic part, when the pressure is transmitted to the elastic part through the anti-overload structure, the elastic part undergoes elastic deformation and is compressed into a round pancake shape to form a rigid support to prevent excessive deformation of the elastic body, thereby preventing excessive deformation of the elastic body.

[0025] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

[0026] Reference Figure 1-3 , provides an elastic body structure for an electronic scale, comprising: an elastic body 1;

[0027] The strain resistor 2 is provided on one end of the elastic body 1 and is used to measure the deformation degree of the elastic body 1;

[0028] The anti-overload structure 3 is provided on the elastic body 1 and is used to prevent the elastic body 1 from being damaged due to overload;

[0029] The plurality of elastic members 4 are arranged in a linear array. The elastic members 4 are provided on the elastic body 1 and contact the anti-overload structure 3 . The elastic members 4 prevent the elastic body 1 from excessive deformation.

[0030] Reference Figure 2A deformation cavity 11 is opened inside the elastic body 1, and the bottom wall of the deformation cavity 11 is fixedly connected to one end of the elastic member 4.

[0031] A waist-shaped groove 12 is provided on the top wall of the inner cavity of the deformation cavity 11, and a plurality of slide grooves 13 are provided on the inner cavity wall of the waist-shaped groove 12. The plurality of slide grooves 13 are arranged in a linear array, and the inner cavities of the waist-shaped groove 12 and the slide groove 13 are movably connected to the anti-overload structure 3.

[0032] The anti-overload structure 3 includes a pressure seat 31, the outer surface of the pressure seat 31 is slidably connected to the inner cavity of the waist groove 12, and is in contact with the elastic member 4. The outer surface of the pressure seat 31 is fixedly installed with a plurality of convex plates 32, and the plurality of convex plates 32 are arranged in a linear array. The outer surface of the convex plate 32 is slidably connected to the inner cavity of the slide groove 13, and the bottom end of the pressure seat 31 is fixedly installed with a plurality of overload columns 33, and the plurality of overload columns 33 are arranged in a linear array. In application, by setting the anti-overload structure 3, when the pressure sensor 10 is pressed, the pressure sensor 10 is pressed. When the pressure is applied to the anti-overload structure 3, the pressure seat 31 receives the pressure and distributes it to the elastic member 4. At the same time, the convex plate 32 on the pressure seat 31 slides along the inner cavity of the slide groove 13 and drives the overload column 33 to move toward the bottom wall of the inner cavity of the deformation cavity 11. The overload column 33 and the bottom wall of the inner cavity of the deformation cavity 11 form a rigid support to prevent the elastomer 1 from being damaged due to overload, and improve the protection performance, thereby preventing the elastomer 1 from being damaged due to overload, thereby improving its protection performance.

[0033] Reference Figure 2-3 The elastic member 4 is a member made of elastic metal material.

[0034] The elastic member 4 is in a spiral shape.

[0035] The height of the overload column 33 is greater than the height of the elastic member 4 in the maximum deformation state and is less than the height of the deformation cavity 11. In application, by setting the elastic member 4, when the pressure is transmitted to the elastic member 4 through the anti-overload structure 3, the elastic member 4 undergoes elastic deformation and is compressed to a round pancake shape to form a rigid support to prevent excessive deformation of the elastomer 1, thereby preventing excessive deformation of the elastomer 1.

[0036] During actual use, when pressure is transmitted to the anti-overload structure 3, the pressure seat 31 bears the pressure and disperses the pressure to the elastic part 4. At the same time, the convex plate 32 on the pressure seat 31 slides along the inner cavity of the slide groove 13 and drives the overload column 33 to move toward the bottom wall of the inner cavity of the deformation cavity 11. The overload column 33 and the inner cavity bottom wall of the deformation cavity 11 form a rigid support to prevent the elastomer 1 from being damaged by overload and improve the protection performance. During this period, the elastic part 4 undergoes elastic deformation and is compressed to a round cake shape to form a rigid support to prevent the elastomer 1 from excessive deformation, thereby preventing the elastomer 1 from being damaged by overload, and thus improving its protection performance. This device can not only prevent the elastomer 1 from being damaged by overload, but also improve the protection performance.
